Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Type: Must support Commutation with Line Driver capability
• Pulses per Revolution: Fixed at 96 PPR or programmable to 96 PPR

The AMT313Q-V qualifies as a substitute because it maintains compatibility across all mandatory mechanical and electrical parameters. The key distinction is that the AMT313Q-V features programmable pulses per revolution, which can be configured to match the 96 PPR specification of the original part.

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on the following factors:

• Product Status Alignment: The AMT313Q-V maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts meet RoHS and REACH requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.
• Mechanical and Electrical Compatibility: All critical parameters—supply voltage, actuator type, mounting configuration, orientation, and termination style—are identical between the two parts.
• Functional Equivalence: The programmable pulses per revolution feature of the AMT313Q-V can be configured to deliver the 96 PPR output of the original part, maintaining system performance.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modifications?

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. The programmable PPR feature must be configured to 96 PPR to match the original part's output specification. No physical modifications are required.

Q: What is the significance of the programmable pulses per revolution feature?

A: The AMT313Q-V allows pulses per revolution to be set during configuration, providing flexibility for different applications. For direct substitution of the AMT303LD-V, this parameter must be programmed to 96 PPR.

Q: Are there differences in packaging between these parts?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination, ensuring compatibility with existing PCB layouts and connector interfaces.

Q: How do the compliance certifications compare?

A: Both parts are RoHS and REACH compliant. The AMT313Q-V meets ROHS3 standards, which represent the current regulatory framework. Both parts have unlimited moisture sensitivity level (MSL 1), indicating no special storage or handling requirements.

Q: Is the AMT313Q-V suitable for the same mounting applications?

A: Yes. Both parts support chassis mount and motor mounting configurations with identical right-angle orientation and 2mm ~ 8mm open center actuator specifications.
